The instruments can be used for overfill protection, for high or low level alarm and in a special configuration for the detection of interfaces, e.g. sand that has settled in water (special model SEDIMENT). The unique, patented single rod designs of our instruments make them work perfectly and reliably even at critical applications where conventional products cause problems due to bridge building, material build-up or rat holing.

PTL Hermann GmbH develops and manufactures vibration type level switches for detecting the presence or absence of powdered or granular solids that are stored in all kinds of silos, hoppers and containers. The products get distributed worldwide. Principle of operation: a vibrating system gets forced to vibrate on its resonance frequency by a piezo crystal drive. If filling material, (bulk solids), covers the vibrating blade of the probe, its vibration gets damped. This is sensed by the electronic circuit and the output switches. When the blade gets uncovered due to declining level, the instrument restarts to vibrate and the output switches back.
